When I got home I downloaded and installed macports using the migration instructions, except that I installed it using the 'installer' command instead of the gui, since I was logged in remotely.  I ran xcode-select --install and agreed to the license.  Everything went smoothly, except that later macports issued warnings about not finding the xcode command line tools for each port that I installed although all of the ports seemed to install properly (there were no failure messages).

If you noticed a "pkg" file being downloaded and installed, then a pre-built binary was used; if instead you noticed a tarball or zipball being downloaded, checksummed, extracted, patched, configured, built, destrooted, installed and activated, then it was built from source. If you did not notice at the time which of those occurred, MacPorts does not record this information anywhere, so it's not possible to know afterward which of these happened.

It doesn't fail the tests on a MacBook Pro that has always had 10.9, and it didn't fail on the Mac Pro before I upgraded to 10.9 and reinstalled macports.

Hmm. Maybe rebuilding would help. The dependencies you got from our binary packages would hopefully not need to be rebuilt. Although we cannot check which of your ports were installed from binaries, if you let us know what MacPorts ports your program is using (i.e. py27-pygtk, I presume, and its dependencies? Any others?) we can check which of those ports have binaries available, and assume that they got used; then you can just rebuild the ones that were built on your machines from source.
